`
`Pursuant to 37 C.F.R. § 42.120 and the Decision to Institute (“Institution
`
`Decision” or “Inst. Dec.”), Patent Owners Paice LLC and the The Abell
`
`Foundation, Inc. (collectively, “Paice”) hereby submit this Response to the Petition
`
`for Inter Partes Review of U.S. Patent. No. 7,237,634 Under 35 U.S.C. § 311 et
`
`seq., and 37 C.F.R. § 42.100 et seq. (“Petition” or “Pet.”) filed by Ford Motor
`
`Company (“Ford”).
`
`I.
`
`INTRODUCTION
`
`U.S. Patent. No. 7,237,634 (“the ’634 patent”), which is the subject of the
`
`present Petition, claims an inventive and novel method of control for a hybrid
`
`electric vehicle that uses road load, setpoint, and the maximum torque output of an
`
`internal combustion engine to determine when to transition between various
`
`operating modes in which the vehicle is propelled by an electric motor, an internal
`
`combustion engine, or both. Ford’s Petition challenges claims 80, 111, 114, 144,
`
`241, 264, 266, 267, 278-280, and 282-291 (“the challenged claims”) as obvious
`
`under 35 U.S.C. § 103. Following Paice’s preliminary response, filed on August
`
`10, 2015, the Board instituted review of each of the challenged claims, except for
`
`80 and 114, based on seven out of eight proposed grounds for obviousness over
`
`U.S. Patent No. 5,343,970 (“Severinsky”) in combination with one or more of U.S.

`

`
`Inst. Dec. at 35. All challenged claims are patentable over the cited grounds for
`
`the reasons set forth herein.
`
`Ford’s arguments with regards to the ’634 patent are fundamentally flawed.
`
`The ’634 patent’s innovative control strategy, using road load and setpoint to
`
`decide when to move between operating modes to maximize efficiency, is absent
`
`in the cited references. Moreover, none of the cited references discloses the road-
`
`load-based hysteresis in determining when to turn the engine on and off, as
`
`required by claims 111 and 144, or limiting the rate of change of torque output of
`
`the engine, as required by claim 241 and its dependent claims. Therefore, for the
`
`reasons detailed more fully herein, the Board should affirm the patentability of
`
`claims 111, 144, 241, 264, 266, 267, 278-280, and 282-291 of the ’634 patent.
`
`II. THE ’634 PATENT
`A. Background of the ’634 Patent
`The ’634 patent (Ex. 1851), entitled “Hybrid Vehicles,” issued on July 3,
`
`2007, from an application with a priority date of September 14, 1998. The ’634
`
`patent discloses embodiments of a hybrid electric vehicle, with an internal
`
`combustion engine, two electric motors and a battery bank. A microprocessor is
`
`employed to control the internal combustion engine, the two electric motors, and
`
`2
`
`

`
`
`
`

`Attorney Docket No: 36351-0015IPD
`
`the battery bank based on the hybrid vehicle’s instantaneous torque requirements
`
`such that the internal combustion engine is only run under high efficiency
`
`conditions. See, e.g., Ex. 1851 at Abstract.
`
`The hybrid vehicle may be operated in a number of modes based on the
`
`vehicle’s instantaneous torque requirements, the engine’s maximum torque output,
`
`the state of charge of the battery, and other operating parameters. In an
`
`implementation of the ’634 patent, the microprocessor employs a hybrid system
`
`control strategy based on sensed and calculated values for system variables that are
`
`evaluated against setpoints and causes the vehicle to operate in various operating
`
`modes pursuant to this control strategy. See, e.g., id. at 40:16-26.
`
`For example, in mode I, the hybrid vehicle is operated as an electric car,
`
`with the traction motor providing all torque to propel the vehicle. Id. at 37:24-32.
`
`As the vehicle continues to be propelled in electric only mode, the state of charge
`
`of the battery may become depleted, and need to be recharged. In this case, the
`
`hybrid vehicle may transition to mode II to recharge the battery, in which the
`
`vehicle operates as in mode I, with the addition of the engine running the
`
`starter/generator motor to provide electrical energy to operate the traction motor
`
`and recharge the battery. See, e.g., id. at 37:32-36. When the internal combustion
`
`engine can be operated in its fuel efficient range to propel the vehicle, the hybrid
`
`vehicle operates in mode IV, with the engine providing torque to propel the

`
`vehicle. Id. at 37:42-44; 38:51-61. If the vehicle requires additional torque, such
`
`as for acceleration or hill-climbing, the vehicle may enter mode V, where the
`
`traction motor provides additional torque to propel the vehicle beyond that
`
`provided by engine 40. Id. at 38:1-8.
`
`B. Claim Construction
`In IPR proceedings, the Board applies the “broadest reasonable
`
`interpretation” standard, which mandates that “[a] claim in an unexpired patent
`
`shall be given its broadest reasonable construction in light of the specification of
`
`the patent in which it appears.” 37 C.F.R. § 42.100(b); see also In re Cuozzo
`
`Speed Techs., LLC, 793 F.3d 1268, 1278 (Fed. Cir. 2015). The Federal Circuit has
`
`recognized, however, that that standard requires that the claims must be read in
`
`light of the specification as it would be interpreted by one of ordinary skill in the
`
`art. In re Suitco Surface, Inc., 603 F.3d 1255, 1260 (Fed. Cir. 2010); see also
`
`Microsoft Corp. v. Proxyconn, Inc., 789 F.3d 1292, 1298 (Fed. Cir. 2015).
`
`“setpoint (SP)”
`
`1.
`A “setpoint” is “a definite, but potentially variable value at which a
`
`transition between operating modes may occur.” In its Institution Decision, the
`
`Board construed “setpoint” as a “predetermined torque value that may or may not
`
`be reset.” Paice respectfully requests that the Board reconsider its construction as
`
`it is unreasonably broad and does not reasonably reflect the disclosure of the ’634
`
`4
`
`

`

`Patent No. 7,237,634
`Patent Owner’s Response
`
`
`
`
`Case IPR2015-00801
`Attorney Docket No: 36351-0015IPD
`
`patent. Instead, the Board should adopt Paice’s construction: a definite, but
`
`potentially variable value at which a transition between operating modes may
`
`occur. The claims and the specification of the ’634 patent make clear that a
`
`“setpoint” is not simply a numerical value divorced from the context of the rest of
`
`the control system. Rather, “setpoint” serves the crucial function of marking the
`
`transition from one claimed mode to another, and in particular, the transition from
`
`propelling the vehicle with the motor to propelling the vehicle with the engine.
`
`See, e.g., Ex. 1851 at 40:41-49.
`
`For example, in claims 1 and 16, the “setpoint” marks the transition between
`
`a mode in which only the motor propels the vehicle, to modes in which the engine
`
`also can be used to propel the vehicle or charge the battery. See Ex. 1851 at claims
`
`1 and 16. Dependent claim 6 similarly recites “…wherein the controller is further
`
`operable to: monitor road load (RL) on the hybrid vehicle over time; and control
`
`transition between propulsion of the hybrid vehicle by the first and/or the second
`
`electric motors to propulsion by the engine responsive to the RL reaching the SP . .
`
`. .” Ex. 1851 at claim 6 (emphasis added); see also id. at claims 8, 11, 19.
`
`Additionally, the specification unambiguously defines “setpoint” as
`
`synonymous with a “transition point” between modes:
`
`[I]n the example of the inventive control strategy discussed above, it is
`repeatedly stated that the transition from low-speed operation to
`highway cruising occurs when road load is equal to 30% of MTO. This

`
`setpoint, referred to in the appended claims as “SP”, and sometimes
`hereinafter as the transition point (i.e., between operation in modes I
`and IV) is obviously arbitrary and can vary substantially, e.g., between
`30-50% of MTO, within the scope of the invention.
`
`Id. at 40:41-49; see also id. at 40:16-26 (“the microprocessor tests sensed and
`
`calculated values for system variables, such as the vehicle’s instantaneous torque
`
`requirement, i.e., the ‘road load’ RL . . . against setpoints, and uses the results of
`
`the comparisons to control the mode of vehicle operation.”); 40:63-65 (“For
`
`example, in response to recognition of a regular pattern as above, the transition
`
`point might be adjusted to 60% of MTO”); 41:4-8 (“It is also within the scope of
`
`the invention to make the setpoint SP to which the road load is compared to control
`
`the transition from mode I to mode IV somewhat ‘fuzzy’ [sic], so that SP may vary
`
`from one comparison of road load to MTO to the next depending on other
`
`variables”); 41:59-63 (“FIG. 9 thus shows the main decision points of the control
`
`program run by the microprocessor, with the transition point between mode I, low-
`
`speed operation, and mode IV highway cruising, set at a road load equal to 30% of
`
`MTO”); 44:24-31 (“Further, as noted above the transition points between modes I,
`
`IV, and V in particular may vary in accordance with the operator's commands…”).
`
`The “setpoint” marks the amount of “road load” at which the claimed
`
`control system actively changes the vehicle from one mode to another (e.g. from
`
`motor propulsion to engine propulsion). The challenged patent recognizes the

`

`Attorney Docket No: 36351-0015IPD
`
`significant efficiencies to be gained by transitioning between motor propulsion to
`
`engine propulsion in response to “road load.” See, e.g., Ex. 1851 at 13: 44-51 (“By
`
`comparison . . . the vehicle’s operating mode—that is, the selection of the source
`
`of torque needed to propel the vehicle—is determined based on the amount of
`
`torque actually required. In this way the proper combination of engine, traction
`
`motor, and starting motor is always available. This apparently simple point has
`
`evidently been missed entirely by the art.”), 13:52-14:2 (noting that prior art
`
`references using vehicle speed to transition between modes “inherently operate the
`
`engine under less efficient conditions”).
`
`The Board’s initial construction of “setpoint” as a “predetermined torque
`
`value that may or may not be reset,” see Inst. Dec. at 11, is incorrect and
`
`unreasonably broad because it fails to recognize that “setpoint” represents a point
`
`at which a transition between different operating modes may occur. The
`
`broadening construction is “divorced from the specification and the record
`
`evidence” and inconsistent with “the one that those skilled in the art would reach.”
`
`See Microsoft, 789 F.3d at 1298 (quoting NTP, 654 F.3d at 1288; Cortright, 165
`
`F.3d at 1358). In essence, the construction covers hybrid vehicle systems where
`
`transitions between modes never occur—a clear error that is fundamentally
`
`contrary to the specification of the ’634 patent. See Fuji Photo Film Co. v. Int'l
`

`
`overly broad construction that is inconsistent with how claim term is used in the
`
`specification). The Board’s “broadest reasonable interpretation” must be
`
`reasonable, and must be in conformity with the invention as described in the
`
`specification. In re Vaidyanathan, 381 Fed. Appx. 985, 995-96 (Fed. Cir. 2010);
`
`see also In re Abbott Diabetes Care Inc., 696 F.3d 1142, 1149 (Fed. Cir. 2012)
`
`(holding that Board’s construction of “electrochemical sensor” was “unreasonable
`
`and inconsistent with the language of the claims and the specification”).
`
`Additionally, SP should not be limited to a torque value—the specification
`
`makes clear that a setpoint is not limited to a torque value and in fact could also be
`
`a measure of the state of charge of the battery.
`
`[T]he microprocessor tests sensed and calculated values for system
`variables, such as the vehicle's instantaneous torque requirement, i.e.,
`the “road load” RL, the engine's instantaneous torque output ITO, both
`being expressed as a percentage of the engine's maximum torque output
`MTO, and the state of charge of the battery bank BSC, expressed as a
`percentage of its full charge, against setpoints, and uses the results of
`the comparisons to control the mode of vehicle operation.
`
`Ex. 1851 at 40:16-26 (emphasis added).
`
`Therefore, Paice respectfully requests that the Board reconsider its
`
`construction and adopt Paice’s construction of “setpoint” to make clear that it is a
`
`value “at which a transition between operating modes may occur.”

`
`to Setpoint and MTO
`
`Each of the challenged claims as properly construed require a comparison of
`
`road load to setpoint and MTO. See Ex. 1851 at claim 80 (“operating at least one
`
`electric motor to propel the hybrid vehicle when the RL required to do so is less
`
`than a setpoint (SP); operating an internal combustion engine of the hybrid vehicle
`
`to propel the hybrid vehicle when the RL required to do so is between the SP and a
`
`maximum torque output (MTO) of the engine, … operating both the at least one
`
`electric motor and the engine to propel the hybrid vehicle when the torque RL
`
`required to do so is more than the MTO”). Because Ford appears intent on
`
`interpreting these limitations in an unreasonably broad manner to remove the
`
`comparison requirement and essentially capture any system where a torque value is
`
`above/below a threshold either by coincidence or otherwise, the Board should
`
`construe these limitations to make clear that the claimed controller (or method of
`
`control) selects operating modes based on a comparison of RL to SP or MTO.
`
`Specifically, the Board should construe “operating at least one electric motor
`
`to propel the hybrid vehicle when the RL required to do so is less than a setpoint
`
`(SP)” as “operating at least one electric motor to propel the hybrid vehicle when a
`
`comparison of the RL to a setpoint (SP) results in a determination that the RL
`
`required to do so is less than a SP.” Second, the Board should construe “operating
`
`an internal combustion engine of the hybrid vehicle to propel the hybrid vehicle

`
`when the RL required to do so is between the SP and a MTO” as “operating an
`
`internal combustion engine of the hybrid vehicle to propel the hybrid vehicle when
`
`a comparison of the RL to a SP and a MTO results in a determination that the RL
`
`required to do so is between the SP and a MTO of the engine.” Third, the Board
`
`should construe “operating both the at least one electric motor and the engine to
`
`propel the hybrid vehicle when the torque RL required to do so is more than the
`
`MTO” as “operating both the at least one electric motor and the engine to propel
`
`the hybrid vehicle when a comparison of the RL to a SP and a MTO results in a
`
`determination that the torque RL required to do so is more than the MTO.”
`
`The intrinsic evidence makes clear that the invention is directed to a control
`
`algorithm for selecting operating modes based on the comparison of road load to
`
`SP and MTO (see Section II.B.1.) such that any other construction would be
`
`“divorced from the specification and the record evidence” and inconsistent with
`
`“the one that those skilled in the art would reach.” Microsoft Corp. v. Proxyconn,
`
`Inc., 789 F.3d 1292, 1298 (Fed. Cir. 2015) (quoting In re NTP, Inc., 654 F.3d
`
`1279, 1288 (Fed. Cir. 2011).
`
`“abnormal and transient conditions”
`
`3.
`The Board should construe “abnormal and transient conditions” as “starting
`
`and stopping of the engine and provision of torque to satisfy drivability or safety
`
`considerations,” to make clear that it does not include “city traffic and reverse

`
`operation.” During the prosecution of the ’097 patent, the patentee distinguished
`
`“abnormal and transient conditions” from “city traffic and reverse operation:”
`
`[T]he Examiner interprets “abnormal and transient conditions” wherein
`the engine can be run at output levels less than SP, the minimum power
`output of the engine under normal circumstances, as “in traffic or city
`driv[ing] too many traffic light so too many stops and reverse
`operation.” In fact, city traffic and reverse operation are normal
`conditions and are explicitly provided for. In both, the vehicle typically
`operates as an electric car, with the traction motor providing the torque
`necessary to propel the vehicle, and with the ICE operated to charge the
`battery when it is discharged. The “abnormal and transient conditions”
`referred to are such conditions as starting the engine, during which
`operation it must necessarily be operated at less than SP for a short time.
`
`Ex. 2801 at 238. However, Ford improperly interprets “abnormal and transient”
`
`conditions broadly as comprising operation in traffic. See Pet. at 32-33.
`
`The Board should construe “abnormal and transient conditions” as “starting
`
`and stopping of the engine and provision of torque to satisfy drivability or safety
`
`considerations.” At a minimum, the Board should reject Ford’s construction and
`
`adopt a construction that does not encompass “city traffic and reverse operation.”
`
`III. ARGUMENT
`Each of the seven instituted grounds of unpatentability should be denied
`
`because the claimed invention is novel and nonobvious. In particular, Ford fails to
`
`provide an adequate obviousness analysis under 35 U.S.C. § 103(a). Moreover,

`
`Severinsky in combination with any or all of Yamaguchi, Lateur, Suga, Vittone,
`
`and Frank fails to disclose or render obvious the RL, SP, road load-based
`
`hysteresis, and “limiting a rate of change” limitations.
`
`Ford’s Conclusory Petition is Deficient Under 35 U.S.C. § 103(a)
`
`A.
`As a preliminary matter, the Petition in its entirety is improper because it does
`
`not perform an adequate obviousness analysis, thus falling short of the requirements
`
`of 35 U.S.C. § 103(a), 35 U.S.C. § 322, and 37 C.F.R. § 42.22(a). Taking Ground 1
`
`as an example, Ford fails to identify the differences between Severinsky and
`
`independent claim 267. As a result, Ground 1 fails to establish that “the differences
`
`between the subject matter sought to be patented and the prior art are such that the
`
`subject matter as a whole would have been obvious at the time the invention was
`
`made to a person of ordinary skill in the art to which the subject matter pertains.”
`
`35 U.S.C. § 103(a); see also KSR lnt’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007)
`
`(explaining that “the scope and content of the prior art are to be determined;
`
`differences between the prior art and the claims at issue are to be ascertained; and
`
`the level of ordinary skill in the pertinent art resolved” (quoting Graham v. John
`
`Deere Co., 383 U.S. 1, 17-18 (1966))).
`
`Specifically, with respect to Ground 1, Ford claims to be performing an
`
`obviousness analysis but for several claim elements does not indicate whether
`
`Severinsky actually discloses or merely renders obvious that claim element. Instead,
`
`12
`
`

`

`Patent No. 7,237,634
`Patent Owner’s Response
`
`
`
`
`Case IPR2015-00801
`Attorney Docket No: 36351-0015IPD
`
`Ford seems to argue that Severinsky discloses each of these claim elements but
`
`curiously concludes each assertion with a statement that a person of ordinary skill in
`
`the art (“POSA”) would have “understood” that those claim elements are present.
`
`See, e.g., Pet. at 12 (“A POSA would have understood that the microprocessor can
`
`deliver ‘all torque required,’ or determine that ‘torque in excess’ of engine
`
`capabilities is ‘required’ only by ‘determining [the] instantaneous road load (RL)
`
`required to propel the hybrid vehicle.’”); Pet. at 14; id. at 16.
`
`As a result, it is entirely unclear whether Ford is advancing anticipation
`
`arguments (e.g., through the doctrine of inherency) or obviousness arguments for
`
`each of these claim elements. If the former, Ford fails to explain why each particular
`
`claim element is necessarily present. Bettcher Indus., Inc. v. Bunzl USA, Inc., 661
`
`F.3d 629, 639 (Fed.Cir.2011) (“Inherency . . . may not be established by probabilities
`
`or possibilities.” (quoting In re Oelrich, 666 F.2d 578, 581 (CCPA 1981))). If the
`
`latter, Ford fails to provide the requisite Graham v. John Deere analysis by failing
`
`to, among other things, identify the differences between the claimed subject matter
`
`and the prior art and identify why those differences would have been obvious to a
`
`POSA. Ford’s conclusory Petition is insufficient to establish obviousness.
`
`B. Grounds 1-8 Should Be Denied—the Prior Art of Record Fails to
`Disclose Using RL to Determine When to Operate the Engine
`
`Grounds 1 through 8 should be denied because the prior art on which Ford
`
`relies does not disclose or render obvious using road load to determine when to

`
`select operating modes. For example, all of the challenged claims require using
`
`road load to determine when to operate the internal combustion engine to propel
`
`the hybrid vehicle and when to operate one or more electric motors. See, e.g., Ex.
`
`1851 at claim 267 (“operating an internal combustion engine of the hybrid vehicle
`
`to propel the hybrid vehicle when the RL required to do so is between the SP and a
`
`maximum torque output”). More specifically, as properly construed (see Section
`
`II.B.2), the claims require the comparison of road load to a setpoint. Ford relies
